    • Correlation study between the performance in different engineering courses and project-based courses 

      Bermejo Broto, Sandra; Bragós Bardia, Ramon; Rey Micolau, Francesc; Pegueroles Vallés, Josep R. (NTNU SEED, 2023)
      Comunicació de congrés
      Accés obert
      In a previous study, already published (Bragós, 2022), we analyzed the correlation between the University access mark to the engineering studies with the grades obtained in projectbased courses and in non-project-based ...

    • Pocketqube L-Band RFI detection payload 

      Podaru, Stefan; Gràcia i Solà, Guillem; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Text en actes de congrés
      Accés obert
      In the last decades, the number of wireless devices has notably increased, and improper RF filtering has resulted in an increase in Radio Frequency Interference (RFI). At L-band this is due to a plethora of reasons: from ...

    • A modified downscaling approach to estimate SMOS soil moisture at high resolution (300 M) using Copernicus Sentinel 3 NDVI 

      Pablos Hernández, Miriam; Portal González, Gerard; Camps Carmona, Adriano José; Vall-Llossera Ferran, Mercedes Magdalena; González-Haro, Cristina; Portabella Arnus, Marcos (Institute of Electrical and Electronics Engineers (IEEE), 2023)
